STM32高分辨率功能非常強(qiáng)大，寄存器數(shù)量非常多，使用起來也比較麻煩，本文使用HRTIM1產(chǎn)生一組互補(bǔ)輸出的PWM
高分辨率定時器的初始化比普通定時器要復(fù)雜得多，
HRTIM_OutputCfgTypeDef HRTIM_TIM_OutputStructure;//配置輸出特性，高低電平等
HRTIM_BaseInitTypeDef HRTIM_BaseInitStructure;//配置基本參數(shù)，這部分和普通定時器一樣
HRTIM_TimerInitTypeDef HRTIM_TimerInitStructure; //配置不同模式
HRTIM_TimerCfgTypeDef HRTIM_TimerWaveStructure;//配置波形參數(shù)，錯誤等
HRTIM_CompareCfgTypeDef HRTIM_CompareStructure;//配置比較寄存器
用以上幾個部分就能產(chǎn)生最簡單的PWM波形
HRTIM_DeadTimeCfgTypeDef HRTIM_DeadtimeStructure;//配置死區(qū)時間和性質(zhì)
HRTIM_FaultCfgTypeDef HRTIM_FaultCfgStructure;//配置錯誤輸入
HRTIM_ADCTriggerCfgTypeDef HRTIM_ADCTrigStructure; //配置ADC觸發(fā)信號
HRTIM_BurstModeCfgTypeDef HRTIM_BurstStructure;//配置Burst模式
等等，還有很多初始化參數(shù)和初始化函數(shù)，基本分為簡單基本功能相關(guān)函數(shù)，波形相關(guān)，輸出相關(guān)，中斷、DMA等模塊；
下面的程序用HRTIM產(chǎn)生一組簡單的PWM波形，50%占空比，無死區(qū)
